Misc 4 Below are given the measures of certain sides and angles of triangles. Identify those which cannot be constructed and, say why you cannot construct them. Construct rest of the triangles.
We know that
Sum of angles of a triangle = 180°
But here,
∠ L + ∠ N = 60° + 120°
= 180°
Sum of two angles cannot be equal to 180°,
as the third angle will be 0°
∴ Δ ABC is not possible
